1 7 '0 all whom it may concern? heretofore possible with the Be it known that FREDERICK W. RoHRs, a citizen of the United States, residin atB-altimore, in the county of Baltimore ?]ity. and Stateof Maryland, has invented new. and useful Improvements in Motor Fuel, of which the following is a specification.

This invention, which is a continuation in By utilizing a heavy fuel comprising the.

ingredients in the proportions-herein set forth, it is obvious that a considerable sav ing will be effected in the consumption of:

' the fuel, as tlie same willnot be drawn off and burned as wastefully "from the jet of the carburetor as the lighter and more volatile fuels.

The motor fuel is composed of the petroleum distillate products, gasoline and kerosene, which are admixed with acetone and benzol iif substantially the proportions below set. forth. I

A motor fuel compounded in accordance I v with myiinvention will greatly increase the mileage per gallonof the fuel, and at'th'e same time -improve the efficiency and in crease the durability of the motorfias it will not corrode or have any other detrimental effect upon the engine parts;

Furthermore, the fuel has the effect of keeping. the carbon in the cylinders in sus pension, reventing its hardening on the metal sur aces, and thus permitting the said free carbon to be expelled through the exhaust.

At temperatures ranging between and 10- 1 1, the following ingredients in the percentages below setforth-have been found to give very advantageous results:

Acetone, approximately 3%.

Benzol, approximately 9%: a 1

Petroleumdistillate, approximately 88 I The percentage of petroleum distillate be ing composed of approximately 85% gasoline and 3% kerosene.

,mi-xedflwith the following ingredients has proved highly satisfactory:

In order that a heavy blended fuel may be obtained at various degrees of temperature, it hasfbeen found desirable to vary the. in-

' creases of benzol for changes in atmospheric temperatures, between.10- F. to 100 F., from approximately 7% to'80% without any variation being made in any of the other ingredients. I

At atemperature of 7 0 F. the fuel when Acetone, approximately 1%. Petroleum distillate, approximately. 49%,. "Benzol, approximately 50%. s. .In the above formula, the composition percentage of petroleum distillate i composed of approximately 1% kerosene, and 48% gasoline. l At a temperature of 100 F., the ingredients in the following percentages have been found 'to' give the best results:

Acetone, approximately 1%. -Benz0 l, approximately 79% Petroleum distillate, approximately 20%. The'petroleum distillate in the above composition being composed of approximately "29% gasoline and 1% kerosene.

The varying of the quantity of benzol used has been found desirable, since benzol at a' very low temperature has a tendency to change from the fluid to the solid state, and

this vcongealing naturally tends to impair the efliciency of the fuel, if not proportionately lessened as the temperature decreases. Conversely, the benzol must be proportionately increased as the temperature rises.

By thus varying the quantity of the benzol I as the temperature changes, a heavy and slowly burning fuel is obtained, which will permit'of a higher spark advance, together with a resultant increase in the compression of the cylinders, and a reduction in the consumption of the fuel.

' The acetone, due to its mobility, tends. to produce better vaporization of the fuel, thus causing the engine to start mucheasier. It also counteracts the heating effect of the benzol, and ssi sts materially in keeping the tei lrli perature of theengine at a proper oint.

e kerosene tends greatly to fac1litate the mixing and blending of the acetonewith the gasoline, and also prevents'the too rapid vaporization of the acetone. Another important advantage residing in the use of kerosene is, that itiacts, in combination with the acetone,' as asolvent of the car-bonde- 'velo'ped in'the' cylinders, and causes the carhon to re ain continuously 1n suspension so thatthe roe-carbon is readily the exhaust gases, which men s in the elimi-.'
